Check with local authorities for building code requirements in your area. Carefully read all Installation Instructions before proceeding with your products application. Observe safety precautions. products are covered by a 50-Year Limited Warranty when installed in accordance with the manufacturer s Installation Instructions. See complete limited warranty on our website at ESTIMATING THE BRICK REQUIRED Determine the amount of products needed by measuring the area to be covered. Measure the length times the height to arrive at the gross square footage of flat area needed. Subtract square footage for window, door and other openings. Measure the linear feet of outside corners to determine the amount of corner pieces needed. One linear foot of corner pieces covers approximately 0.80 square feet of flat area. Subtract the flat area covered by the linear feet of corner pieces from the square footage of flat area required. You may wish to obtain some extra brick to allow for cutting and trimming. Formula: Length x Height = Wall Area Window Width x Window Height = Window Area Lineal Feet of Corners Required x 0.80 = Wall Area Covered by Corners Wall Area Window Area Wall Area Covered by Corners= Square Ft.

Apply 1 " to 4" scratch coat and allow to dry 48 hours (Fig. ). * Failure to properly caulk fl ashing as described in these installation directions may result in water damage to the structure. INSTALLING CULTURED BRICK AT GROUND LEVEL Keep the finished edge of the product a minimum of 4" above grade if earth or " above pavement. Use a " x 4" leveling strip (straightedge) or weep screed/ flashing. Framed (wood or metal) applications are required by code in many jurisdictions to have weep screed or a weeped casing bead, at the base of the wall or foundation transition. This will: Provide drainage as required by applicable building code. Avoid possible staining of the stone by soils containing alkali or other minerals. Lay Out Wall Area Choose the type of wall pattern desired. Allowing for a mortar joint of approximately 1 ", calculate and mark off the number of courses required. Adjust joint size to minimize horizontal cutting. Run level guide lines to ensure proper placement of bricks. Mix brick from several boxes at a time to achieve a pleasing blend of color and texture. WEATHER RESISTANT BARRIER/WATER RESISTIVE BARRIER (WRB) When installing manufactured brick veneer, in an exterior application requiring a WRB, it is recommended that two separate layers of WRB be used. Each layer of WRB should meet the requirements for Water Resistive Barrier (Grade D) as defined by ICC Acceptance Criteria AC-8, or ASTM E 556/E 556M. Installation of the WRB should follow instructions provided by specific manufacturer. WATERTABLE/SILL INSTALLATIONS Watertables/Sills provide a transition piece between a stone wainscot and other exterior finishes and for water runoff. They can also be used as a windowsill. Install using galvanized metal support brackets (Simpson Strong Tie A-1 or other galvanized right-angle bracket with holding Running Bond Stack Bond Flemish Bond Wetting Exterior Walls Dampen concrete, masonry or stucco wall surfaces with water prior to the application of the brick. Wetting the Brick The back of the brick should be completely damp, but free from surface water at the time of application.

3 MORTAR NOTE: Weather Conditions Applications should be protected from temperatures below 40 F as mortar will not cure properly under such conditions. Do not use antifreeze compounds to lower the freezing point of mortar. See International Building Code 104. for cold weather construction requirements. A. Mixing Mortar/Grout Using Premixed Type N or Type S mortar or components from Table, mix to a firm, moist consistency. Mortar that is too dry and crumbly will not provide proper bond. Mortar that is too wet will be weak and messy. Table Proportions for Mortar Parts By Volume Mortar type B. Mortar Color Tinting mortar complements the color of the brick being installed. Example: Use tan mortar with earth-tone bricks. This will greatly enhance the appearance of the finished installation. Regular mortars can be tinted to complement your product using iron oxide pigments available from your dealer. APPLYING CULTURED BRICK PRODUCTS A. Starting Point Apply mortar and brick working from the bottom up, or from the top down. Working from the top down may help avoid splashing previously applied brick with dripping mortar. B. Applying Mortar to Prepared Surface Area Using a plasterer s or mason s trowel (Fig. 5 and 6), apply mortar 1 " to 4 " thick to prepared surface area. Do not spread more than a workable area (5 to 10 sq. ft.) so that mortar will not set up before brick is applied. Figure 5 Portland Cement or Blended Cement Apply mortar using a plasterer s trowel. Masonry Cement Type N Masonry Cement Type S Figure 6 Hydrated Lime or Lime Putty Apply mortar using a mason s trowel. C. Setting the Bricks Press each brick into the mortar setting bed fi rmly enough to squeeze some mortar out around the brick s edges. Apply pressure to the brick to ensure a good bond. Ensure complete coverage between the mortar bed and back surface of the brick. Mortar may also be applied to the entire back of the brick (Fig. 7). When brick is installed correctly, lath will not be visible. Figure 7 Mortar applied to entire back of brick. Care must be taken to avoid smearing mortar on surface of brick. Accidental smears or mortar droppings should be removed using a whisk broom only after mortar has become crumbly. Aggregate N 1 I 4 1 to 6 N I 1 4 to S I 1 4 to D. Install Corner Pieces First If your application requires corner pieces, apply these fi rst. Notice that the corner pieces have a long and a short leg. Alternate these in opposite directions (Fig. 8). E. Inside Corners When using a running bond, set full bricks to half bricks at inside corners, alternating lengths in each course. F. Install Flat Brick Start at the end of the wall to complete one horizontal course of brick. Work across the surface area one course at a time. Keep courses level and plumb by using a carpenter s level to check each course as it is laid. Apply flat pieces. Figure 8 Apply corner pieces first alternating long and short legs in the opposite directions. G. Keep Your Mortar Joints Consistent Place the individual bricks close together, creating 1 " uniform joints between them. Cut trim as required to achieve consistent width in the mortar joints. WORKING WITH MASONRY ADHESIVE (INTERIOR ONLY) On some interior projects, the use of masonry adhesive offers a fast and easy alternative to mortar. NOTE: Do not wet brick when installing with adhesive. Do not install water resistive barrier. Recommended adhesives include: Loctite PowerGrab, Liquid Nails Marble and Granite. Table Interior Surfaces Preparation Required When Using Masonry Adhesive Recommended Surfaces Preparation Alternatives Non-recommended Surfaces Masonry adhesive may be applied over most clean and structurally sound interior surfaces such as plywood, concrete block and concrete. Loose surface materials should be removed. Sanding may be required on very smooth surfaces to achieve a good bonding surface. As an alternative, plywood sheathing fastened to the wall studs over existing or removed surface materials will provide an inexpensive and effective application substrate. Masonry adhesive is NOT RECOMMENDED for application over smooth textured tile, metal, wallpaper, drywall, some types of paint or surfaces that are continually damp.

4 MASONRY ADHESIVE WITH GROUTED JOINT Setting Brick With Masonry Adhesive Place adhesive as per adhesive manufacturer s instructions on the back of each brick in 1 4 " bead, perpendicular to grooves on brick (Fig. 9). Press and wiggle bricks into place on wall surface until they bottom out. Set bricks level and plumb, completing one row at a time. Apply grout between bricks using a mortar bag. TYPICAL INSTALLATIONS Wood Frame: A. Cutting and Trimming Make half bricks by scoring the back side with a hacksaw and snapping the brick in half. SAFETY GLASSES AND A DUST MASK (1) SHOULD ALWAYS BE WORN WHEN CUTTING ANY CULTURED BRICK PRODUCTS. Vertical or horizontal cuts can be made using a table saw, circular saw or small grinder equipped with diamond or carborundum blade. SAFETY GLASSES AND A DUST MASK SHOULD ALWAYS BE WORN WHEN CUTTING ANY CULTURED BRICK PRODUCTS. GROUTING AND FINISHING JOINTS A. Grouting Joints Use a grout bag to fill any unmortared spaces between bricks. Figure 9 Apply adhesive to the back of each brick. In sequence: (1) sheathing, () two layers of water resistive barrier, () galvanized metal lath, (4) mortar, (5) thin brick veneer, (6) mortar joint. Rigid Foam Insulation: In sequence: (1) rigid foam insulation, () two layers of water resistive barrier, () metal lath, (4) scratch coat, (5) mortar setting bed, (6) thin brick veneer, (7) mortar joint. Masonry or Concrete: Use a grout bag to fi ll in joints. Care must be taken to avoid smearing mortar on surface of brick. Accidental smears or mortar droppings should be removed only after mortar has become crumbly. Use a whisk broom or dry bristle brush. Never use a wet brush or wire brush. B. Finishing Joints When the mortar joints have become firm ( thumb print dry), they should be pointed up with a metal jointing tool. Rake out excess mortar, compact and seal edges around bricks. (Setting time will vary depending on wall surface and climatic conditions.) In sequence: (1) mortar applied directly to untreated, unpainted masonry, concrete or stucco, () thin brick veneer, () mortar joint. Corner Preparation: 1 Finish mortar joints with a jointing tool. 1 CORRECT INCORRECT Mortar joints are uniform. Mortar joints are not uniform. Jointing is concaved. Incorrect tooling of joints joints raked too deeply. Water resistive barrier and lath must continuously wrap a minimum of 16" at outside and inside corners and fasten at a framing member. Lap water resistive barrier a minimum of 4" at vertical and " at horizontal lap joints. Lap lath a minimum of 1" at vertical and horizontal seams.

5 GENERAL INFORMATION Cleaning Dirt, etc., may be removed by using a strong solution of granulated soap or detergent and water with a bristle brush. Do not use a wire brush as it will cause damage to the surface. Rinse immediately with fresh water. For help with serious cleaning problems, contact your local dealer. Do not attempt to clean using acid or acid-containing products, power-washing, sandblasting or wirebrush cleaning. Salt and De-Icing Chemicals Because all concrete and masonry are vulnerable to damage by salt, products are not warranted against damage incurred from salt or other chemicals used to remove snow or ice. Do not use de-icing chemicals on areas immediately adjacent to a Cultured Brick veneer application. Scuffing Scuffing occurs on all brick. Occasionally some scuffing will occur on the surface of products. This can enhance the appearance of your veneer installation. Some scuff marks can be removed by cleaning as described above. Efflorescence Efflorescence is a water-soluble salt that is deposited on the surface of stucco, concrete, brick and other masonry products by the evaporation of water from the wall. On rare occasions efflorescence will occur on products. To remove efflorescence, allow the brick to dry thoroughly, then scrub vigorously with a stiff bristle brush and clean water. Rinse thoroughly do not use a wire brush. For more difficult efflorescence problems, scrub thoroughly with a solution of 1 part white household vinegar to 5 parts water. Rinse thoroughly. For unusually difficult cleaning problems, contact your local dealer. Sealers Sealers are not necessary on products. However, some customers use sealers to help prevent staining in applications prone to smoke, soot, dirt or water splashing. If you choose to use a sealer, make sure it is a silane-based, breathable sealer. Take note that sealers may darken the color of the brick. A sealer may also slow the natural movement of moisture out of the brick and increase the possibility of efflorescence and/or spalling. For information regarding actual performance or application of sealers, contact the manufacturer of the sealer directly. Use of Below Water Levels veneer is a lightweight concrete material and will not deteriorate from exposure to fresh liquid water. The use of veneer below water level, in which the water is chlorinated, treated with chemicals or dirty will likely cause discoloration as it would on any concrete, natural stone or other materials. veneer concrete and many natural stone materials are subject to potential damage from adverse freeze thaw conditions. Water should be drained below susceptible materials prior to freezing temperatures. Pressure and abrasion from constant fast flowing water may cause some surface deterioration as it would on other concrete 5 materials. The surfaces of concrete and many other materials may be affected by exposure to extensive saltwater conditions. veneer should not be considered a waterproof material. INCORPORATE GOOD BUILDING PRACTICES Building Code Requirements Building code requirements vary from area to area. Check with local authorities for building code requirements in your area. Carefully read all Installation Instructions before proceeding with your veneer application. Exterior Applications Make sure that the application of products and the structure they are being applied to, incorporate good building practices. Rigid, corrosion-resistant flashing shall be installed at all wall penetrations. Flashing type and locations shall be in accordance with the requirements of the applicable building code. On exterior applications, the incorrect installation or absence of flashing, cant strips, gutters and downspouts may result in diversion of water runoff onto finished surface areas. Masonry and other building products subjected to these conditions may develop staining and, when combined with severe freeze-thaw conditions, may eventually cause surface damage. The application of products under these conditions is not recommended. Rainscreen Statement Some building codes require a rainscreen behind cladding materials, including manufactured brick veneer. If you are installing manufactured brick veneer in one of these jurisdictions, or are concerned about extreme weather conditions, it is recommended that you choose a rainscreen system that can achieve the following: The system should create a space with a minimum depth of /8 (10mm) and maximum depth of ¾ (19mm). The materials should be corrosion and rot resistant. Unless otherwise designed to manage moisture vapor, the system should be vapor open. If rainscreen space is created with a material other than solid strapping/ furring attached directly to framing, the following must be considered. Lath fasteners must be capable of supporting the weight of the fi nished wall cladding system considering the unsupported/ cantilevered portion of fastener that is equal to the thickness of the rainscreen materials. Overhead Application Overhead, horizontal or sloped applications are not included in our building code evaluation reports or acceptances. These applications often require special approval/ inspections by local building code inspectors. Contact your architect or engineer for assistance designing these installations. Installation Over Thick Foam Installation over foam board thicker than 1 " may require special fasteners. Consult your architect or engineer for assistance designing a thick foam installation. Capping Off the Exposed Top of Exterior Walls To achieve a finished architectural look on horizontal or sloping top areas of exterior walls, piers, retaining walls or other surfaces, the use of Cultured Stone Capstones or

6 a poured-in-place concrete cap must be used to provide adequate run-off protection to the wall areas. Caps should extend approximately 1" " beyond the finished brick surface. corner pieces, flat pieces, or hearthstones must not be used to cap walls. Retaining Walls All retaining walls must be waterproofed at the fill side. Wall construction should incorporate proper use of granular backfill and provisions for good drainage. A continuous longitudinal drain along the back of the wall set in drain rock is recommended. Chimney Cap All chimney chases must be capped with a one-piece cap that extends 1" " beyond the finished brick surface to prevent water from entering the wall system. Chimney or chase construction should incorporate proper flashing.
